State the layers of WORM drive? How data is recorded in WORM drive? Input signal is fed to laser diode Laser beam strikes the three recording layers Laser beam is absorbed by Bismuth-Tellurium layer and generates heat The heat diffuses the atoms in the recording layers and forms a four element alloy Sb, Se, Bi, and Te which is the recorded area. How data is read from WORM drive? Weak Laser beam is focused to the disk It is not absorbed due to reduced power level and reflected back The beam splitter mirror and lens arrangement sends the reflected beam to Photo detector The Photo sensor detects the beam and converts it into electrical signal

Computer graphics are pictures and films created using computers. Usually, the term refers to computer generated image data created with help from specialized graphical hardware and software.

It is a vast and recent area in computer science. The phrase was coined in 1. Verne Hudson and William Fetter of Boeing. It is often abbreviated as CG, though sometimes erroneously referred to as computer generated imagery CGI.

Some topics in computer graphics include user interface design, sprite graphics, vector graphics, 3. D modeling, shaders, GPU design, implicit surface visualization with ray tracing, and computer vision, among others. The overall methodology depends heavily on the underlying sciences of geometry, optics, and physics.

Computer graphics is responsible for displaying art and image data effectively and meaningfully to the user. Add and Manipulate Text and Graphics Create areas of text and graphics with tools.

It gives you everything. Adobe is changing the world through digital experiences. We help our customers make, manage, measure and monetize their content across every channel and screen. This page provides an annotated, topicbased collection of available resources for statistics, statistical graphics, and computation related to research, data.

It is also used for processing image data received from the physical world. Computer graphic development has had a significant impact on many types of media and has revolutionized animation, movies, advertising, video games, and graphic design generally.

OvervieweditThe term computer graphics has been used in a broad sense to describe almost everything on computers that is not text or sound. Typically, the term computer graphics refers to several different things the representation and manipulation of image data by a computerthe various technologies used to create and manipulate imagesthe sub field of computer science which studies methods for digitally synthesizing and manipulating visual content, see study of computer graphics.

Free Web site icons in a variety of graphics formats. Oblivion Insert Disc Crack Fix. Contains information on ongoing research projects, academic information, job news, and academic resource links. Today, computer graphics is widespread. Such imagery is found in and on television, newspapers, weather reports, and in a variety of medical investigations and surgical procedures. A well constructed graph can present complex statistics in a form that is easier to understand and interpret.

A further evolution of the specification, with considerable internal restructuring, finally. ASUS is a leading company driven by innovation and commitment to quality for products that include notebooks, netbooks, motherboards, graphics cards, displays. Learn how to incorporate the powerful MASH procedural animation toolsincluded with the Maya Extension 2into your Maya workflow and build more dynamic.

In the media such graphs are used to illustrate papers, reports, theses, and other presentation material. Many tools have been developed to visualize data. Computer generated imagery can be categorized into several different types two dimensional 2.

D, three dimensional 3. D, and animated graphics. As technology has improved, 3. D computer graphics have become more common, but 2. D computer graphics are still widely used. Computer graphics has emerged as a sub field of computer science which studies methods for digitally synthesizing and manipulating visual content.

Over the past decade, other specialized fields have been developed like information visualization, and scientific visualization more concerned with the visualization of three dimensional phenomena architectural, meteorological, medical, biological, etc. HistoryeditIntroductioneditThe precursor sciences to the development of modern computer graphics were the advances in electrical engineering, electronics, and television that took place during the first half of the twentieth century.

Screens could display art since the Lumiere brothers use of mattes to create special effects for the earliest films dating from 1. The first cathode ray tube, the Braun tube, was invented in 1. Nevertheless, computer graphics remained relatively unknown as a discipline until the 1. World War II period during which time the discipline emerged from a combination of both pure university and laboratory academic research into more advanced computers and the United States militarys further development of technologies like radar, advanced aviation, and rocketry developed during the war.

New kinds of displays were needed to process the wealth of information resulting from such projects, leading to the development of computer graphics as a discipline. Douglas T. Ross of the Whirlwind SAGE system performed a personal experiment in which a small program he wrote captured the movement of his finger and displayed its vector his traced name on a display scope.

One of the first interactive video games to feature recognizable, interactive graphics Tennis for Two was created for an oscilloscope by William Higinbotham to entertain visitors in 1. Brookhaven National Laboratory and simulated a tennis match. Ross innovated again while working at MIT on transforming mathematic statements into computer generated machine tool vectors, and took the opportunity to create a display scope image of a Disneycartoon character.

Electronics pioneer Hewlett Packard went public in 1. Stanford University through its founders, who were alumni. This began the decades long transformation of the southern San Francisco Bay Area into the worlds leading computer technology hub now known as Silicon Valley. The field of computer graphics developed with the emergence of computer graphics hardware.

Further advances in computing led to greater advancements in interactive computer graphics. The TX 2 integrated a number of new man machine interfaces. A light pen could be used to draw sketches on the computer using Ivan Sutherlands revolutionary Sketchpad software. Using a light pen, Sketchpad allowed one to draw simple shapes on the computer screen, save them and even recall them later.

The light pen itself had a small photoelectric cell in its tip. This cell emitted an electronic pulse whenever it was placed in front of a computer screen and the screens electron gun fired directly at it. By simply timing the electronic pulse with the current location of the electron gun, it was easy to pinpoint exactly where the pen was on the screen at any given moment. Once that was determined, the computer could then draw a cursor at that location.

Sutherland seemed to find the perfect solution for many of the graphics problems he faced. Even today, many standards of computer graphics interfaces got their start with this early Sketchpad program. One example of this is in drawing constraints. If one wants to draw a square for example, they do not have to worry about drawing four lines perfectly to form the edges of the box. One can simply specify that they want to draw a box, and then specify the location and size of the box.

The software will then construct a perfect box, with the right dimensions and at the right location. Another example is that Sutherlands software modeled objects not just a picture of objects. In other words, with a model of a car, one could change the size of the tires without affecting the rest of the car. It could stretch the body of car without deforming the tires. The phrase computer graphics itself was coined in 1.

William Fetter, a graphic designer for Boeing. This old quote in many secondary sources comes complete with the following sentence Fetter has said that the terms were actually given to him by Verne Hudson of the Wichita Division of Boeing.
